Abstract

L'invention concerne des systèmes auxiliaires assurant le fonctionnement d'une pile à combustible alcaline (AFC), en particulier un procédé et un dispositif de purification d'air par sorbant s'utilisant dans une AFC faite de dioxyde de carbone. Selon l'invention, un procédé de purification d'air de la pile à combustible comporte les étapes consistant à : faire passer l'air de départ à travers un adsorbeur contenant un adsorbant fait de dioxyde de carbone, et à régénérer ensuite l'adsorbant ; régénérer, après utilisation, l'adsorbant comprenant des oxydes hydratés de métaux de transition, à une température comprise entre 60 et 120 ·C, par l'air consommé dans la pile à combustible ; chauffer l'air chargé en vue de la régénération jusqu'à obtention d'une humidité relative comprise entre 15 et 85 %. Un dispositif de purification d'air de piles à combustible comprend un ventilateur relié par des conduites et des soupapes d'arrêt à des adsorbeurs pourvus d'un adsorbant fait de dioxyde de carbone et reliés à une entrée d'air de la pile à combustible. La soupape d'arrêt est prévue sous forme de commutateurs assurant la connexion séquentielle de l'entrée et de la sortie d'un des adsorbeurs avec le ventilateur et une entrée d'air de la pile à combustible, respectivement ; et de la sortie de l'autre adsorbeur, par un élément chauffant, avec la sortie d'air de la pile. L'invention concerne un dispositif pour purifier l'air de piles à combustible, qui comprend un ventilateur relié au moyen de conduites à des adsorbeurs comportant un adsorbant fait de dioxyde de carbone et à une entrée d'air d'une pile à combustible, le dispositif étant conçu de sorte que les adsorbeurs, séparés les uns des autres par des cloisons, sont placés dans un corps pouvant tourner autour d'un axe longitudinal et être séquentiellement reliés, à une entrée, au ventilateur ; et à une sortie, par un élément chauffant, à une sortie d'air de la pile. Les adsorbeurs peuvent comporter un adsorbant comprenant de l'oxyde de zirconium hydraté. Une isolation thermique peut être prévue à l'intérieur des adsorbeurs et des éléments chauffants.
